Note on Haze (ASTM D1003-97):
With some instrument types, the illumination/observation system may not satisfy the
definition of haze (ASTM D1003-97). However, this presents no problem as long as
the value is used as a relative value.

Notes concerning displayed values:
The SpectraMagic NX software enhances calculation accuracy by performing inter-
nal calculations with numbers greater in magnitude than those actually displayed.
Consequently, the least significant digit displayed may differ from that of the instru-
ment by one digit due to rounding or color space conversion.
Because the tolerance judgement calculation and graph-plotted points are also pro-
cessed with numbers greater in magnitude than those actually displayed, the judge-
ment result or plotted points may differ from those obtained with the values
displayed on the instrument.
Each colorimetric value of the data measured with a spectrophotometer or obtained
by manual input of spectral reflectance data is calculated from spectral reflectance.
Each colorimetric value of the data measured with a colorimeter or obtained by man-
ual input of colorimetric data is calculated from XYZ data. As a result, the colorimet-
ric value of the average value obtained by the manual averaging measurement or by
the averaging of list data may differ from the average of colorimetric values dis-
played in the list.
